Abstract
Background and Objectives: Diabetes mellitus is the most common disease of endocrine system. Due to diabetes long-term complications many patients undergo operations. Hemodynamic instability during induction of anesthesia due to diabetic autonomic neuropathy is common. The present study aimed at assessing hemodynamic responses to tracheal intubation in diabetic patients.
Materials and Methods: In a descriptive-cross sectional and double blind study, 30 diabetic and 30 non-diabetic patients referred for ophthalmic surgeries were studied in two groups regarding heart rate, systolic, diastolic and mean arterial blood pressures before anesthesia, during laryngoscopy, during intubation, and at 1st, 3rd and 5th minutes after intubation. Age, gender, drug effects, complications, duration of the disease, autonomic neuropathy and hypertension were also noted.
Results: Five patients (16.66%) had diabetic autonomic neuropathy. Regarding the hemodynamic responses, there were no significant differences between diabetic and non-diabetic patients; however they significantly differed within each group.
Conclusion: The presence of diabetic autonomic neuropathy seems not to give rise to greater changes and hemodynamic instability. Hemodynamic stability is observed during anesthesia induction and intubation in these patients.
